1. Foliar Fertilization of Soybeans in MissouriSoybeans may benefit from foliar fertilization during the reproductive phase of growth. Foliar fertilizers consisting of factorial combinations of boron, calcium, magnesium and phosphorus were applied to soybeans every other week for eight weeks beginning at flowering at three locations. The foliar fertilization treatment containing B+Mg (1.0 lb/acre B + 2.0 lb/acre Mg total) and split into four applications at Mt. Vernon and the Delta Center increased yields by 8 and 4 bulacre, respectively. The... |
2. Phosphorus Fertilization Improves the Quality of Stockpiled Tall FescueStockpiling tall fescue is a recommended practice for increasing profitability of beef cattle production. However, little information is available on the mineral element composition of tall fescue pastures stored for winter grazing. In fact. analysis of the few studies reported indicates that both phosphorus and nlagnesium levels may be low in stockpiled tall fescue by late winter. The objective of this study was to determine the impact of phosphorus fertilization on improving the nutrient quality... |
3. Cover Crops, Manure, and NitrogenFall seeded cover crops can offer soil and water conservation benefits to dairy-based cropping systems. However, uptake by these fall cover crops can also limit nitrogen availability from the manure to the next crop. Field research projects throughout the state of Wisconsin have been conducted to assess how cover crop specie, biomass, and N uptake influence the amount of supplemental N needed to fertilize the following corn crop to maximize yield. Fall seeded cover crops that winter kill (spring... M. Ruark, A. Waggoner |
4. Soil Carbon Additions Improve Soil Nutrient Cycling and Yield of CornIncreasing soil organic matter and the associated soil carbon is known to positively influence nutrient cycling, and agronomic practices such as conservation tillage and cover crops can facilitate soil carbon increases in the long term. Alternatively, the direct addition of carbon amendments to the soil may serve as an alternative solution for enhancing nutrient cycling in the short-term, which was the basis for this research. Our objective was to assess the potential of granular carbon amendments... D. Danzl, D. Below, D. Sible |
